FOREWORD
The National Eutrophication Survey was initiated in 1972 in
response to an Administration commitment to investigate the nation-
wide threat of accelerated eutrophication to fresh water lakes and
reservoirs.
OBJECTIVES
The Survey was designed to develop, in conjunction with state
environmental agencies, information on nutrient sources, concentrations,
and impact on selected freshwater lakes as a basis for formulating
comprehensive and coordinated national, regional, and state management
practices relating to point-source discharge reduction and non-point
source pollution abatement in lake watersheds.
ANALYTIC APPROACH
The mathematical and statistical procedures selected for the
Survey's eutrophication analysis are based on related concepts that:
a. A generalized representation or model relating
sources, concentrations, and impacts can be constructed.
b. By applying measurements of relevant parameters
associated with lake degradation, the generalized model
can be transformed into an operational representation of
a lake, its drainage basin, and related nutrients.
c. With such a transformation, an assessment of the
potential for eutrophication control can be made.
LAKE ANALYSIS
In this report, the first stage of evaluation of lake and water-
shed data collected from the study lake and its drainage basin is
documented. The report is formatted to provide state environmental
agencies with specific information for basin planning [§303(e)L water
quality criteria/standards review [§303(c)], clean lakes [§314(a,b)],
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
-------
iii
Beyond the single lake analysis, broader based correlations
between nutrient concentrations (and loading) and trophic condi-
tion are being made to advance the rationale and data base for
refinement of nutrient water quality criteria for the Nation's
fresh water lakes. Likewise, multivariate evaluations for the
relationships between land use, nutrient export, and trophic
condition, by lake class or use, are being developed to assist
in the formulation of planning guidelines and policies by EPA
and to augment plans implementation by the states.
ACKNOWLEDGMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Michigan Department of
Natural Resources for professional involvement and to the
Michigan National Guard for conducting the tributary sampling
phase of the Survey.
A. Gene Gazlay, former Director, and David H. Jenkins, Acting
Director, Michigan Department of Natural Resources; and Carlos
Fetterolf, Chief Environmental Scientist, and Dennis Tierney,
Aquatic Biologist, Bureau of Water Management, Department of Natural
Resources, provided invaluable lake documentation and counsel during
the course of the Survey. John Vogt, Chief of the Bureau of Environ-
mental Health, Michigan Department of Public Health, and his staff
were most helpful in identfying point sources and soliciting municipal
participation in the Survey.
Major General Clarence A. Schnipke (Retired), then the Adjutant
General of Michigan, and Project Officer Colonel Albert W. Lesky,
who directed the volunteer efforts of the Michigan National Guardsmen,
are also gratefully acknowledged for their assistance to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
On the basis of Survey data, it is concluded that Lake
Charlevoix is oligotrophic. Of the 35 Michigan lakes sampled
in November when essentially all were well-mixed, only one
(Higgins Lake) had better overall water quality. Only five
lakes had less mean inorganic nitrogen, only three lakes had
less mean chlorophyll a^ only one lake had greater Secchi disc
transparency, three lakes had the same low algal assay control
yield (but none were lower), and only one lake had less mean
total and dissolved phosphorus*.
Some depression of oxygen (to about 6 mg/1) with depth
(below 35 feet) was noted at stations 3 and 4 in Seotember,
1972.
B. Rate-Limiting Nutrient:
The algal assay results and the lake data show that Lake
Charlevoix is phosphorus limited.
C. Nutrient Controllability:
1. Point sources—During the sampling year, Lake Charle-
voix received a total phosphorus load at a rate less than that
proposed by Vollenweider (in press) as "permissible"; i.e.,
* See Appendix A.
-------
less than an oligotrophic rate (see page 14). Of this load,
the Boyne City wastewater treatment plant contributed about
14%.
While the present phosphorus loading rate is relatively
low, and 80% phosphorus removal is required at the only known
point source impacting the lake (Boyne City), every effort
should be made to reduce all phosphorus inputs to the lowest
practicable level to ensure that the existing high quality
of Lake Charlevoix is maintained.
2. Non-point sources (see page 14)—Attention is called
to the non-point phosphorus export rate of the Jordan River.
During the sampling year, the rate of P-export of this stream
markedly exceeded the non-point phosphorus rates of any of the
other five streams sampled. As far as is known, there are no
point sources in the Jordan River drainage, and it seems unlikely
that the geological characteristics of the drainage would differ
much from adjacent drainages. It appears it would be desirable
to review the cultural practices in the Jordan River drainage
basin in more detail than was possible in this Survey, particu-
larly since the south arm of the lake is much shallower than the
main body (Tierney, 1974) and is more susceptible to nutrient
inputs.

III. LAKE WATER QUALITY SUMMARY
Lake Charlevoix was sampled three times during the open-water season
of 1972 by means of a pontoon-equipped Huey helicopter. Each time,
samples for physical and chemical parameters were collected from four
stations on the lake and from a number of depths at each station (see
map, page v). During each visit, a single depth-integrated (15 feet to
surface) sample was composited from the four stations for phytoplankton
identification and enumeration; and during the second visit, a single
five-gallon depth-integrated sample was composited for algal assay.
Also each time, a depth-integrated sample was collected from each of
the stations for chlorophyll ^analyses. The maximum depths sampled
were 42 feet at station 1, 85 feet at station 2, 100 feet at station 3,
and 71 feet at station 4.
The results obtained are presented in full in Appendix C, and the
data for the fall sampling period, when the lake essentially was well-
mixed, are summarized below. Note, however, the Secchi disc summary
is based on all values.
For differences in the various parameters at the other sampling
times, refer to Appendix C.

Discussion -
The control yield of the as
cornutum. indicates that the potential primary productivity
of Charlevoix Lake was low at the time the assay sample was
-------
8
collected. Also, the increasing yields with increasing
increments of orthophosphorus (to about 0.020 mg/1) show
that the lake was phosphorus limited at that time. Note
that the addition of only nitrogen resulted in a yield no
greater than the control yield.
The conclusion of phosphorus limitation is supported
by the lake data. Nitrogen to phosphorus ratios were
greater than 35 to 1 at all sampling times.
-------
IV. NUTRIENT LOADINGS
(See Appendix D for data)
For the determination of nutrient loadings the Michigan National'
Guard collected monthly near-surface grab samples from each of the
tributary sites indicated on the map (page v), except for the high
runoff months of April and May when two samples were collected. Samp-
ling was begun in October, 1972, and was completed in September, 1973.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Michigan District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were deter-
mined by using a modification of a U.S. Geological Survey computer
program for calculating stream loadings*. Nutrient loadings for unsam-
pled "minor tributaries and immediate drainage" ("II" of U.S.G.S.) were
2
estimated by using the means of the nutrient loads, in Ibs/mi /year, at
stations B-l, D-l, E-l, F-l, and G-l and multiplying the means by the
2
II area in mi .
The operator of the Boyne City wastewater treatment plant provided
monthly effluent samples and corresponding flow data. The effluent
from the East Jordan stabilization pond is disposed of on land with no
discharge to Lake Charlevoix.

E. Yearly Loading Rates:
In the following table, the existing phosphorus loading
rates are compared to those proposed by Vollenweider (in press).
Essentially, his "dangerous" rate is the rate at which the
receiving water would become eutrophic or remain eutrophic;
his "permissible" rate is that which would result in the
receiving water remaining oligotrophic or becoming oligo-
trophic if morphometry permitted. A mesotrophic rate would
be considered one between "dangerous" and "permissible".
